The 1906 San Francisco earthquake was a big earthquake that hit San Francisco on April 18, 1906.[3] It was felt from Los Angeles to Oregon and Nevada. The earthquake was about a 7.9 on the Richter scale. Around 3,000 people were killed and between 227,000 and 300,000 people were left homeless.[4] There were also fires because gaspipes were destroyed, and the gas caught on fire. Over 80% of the city was destroyed by the earthquake and fires that came later. The city is on the San Andreas Fault, which slid, causing the earthquake. Many people looted so then the Army had to come in to keep the peace.
